Time series models relating short-term changes in air pollution levels to daily mortality counts typically assume that the effects of air pollution on the log relative rate of mortality do not vary with time. However, these short-term effects might plausibly vary by season. Changes in the sources of air pollution and meteorology can result in changes in characteristics of the air pollution mixture across seasons. The authors develop Bayesian semi-parametric hierarchical models for estimating time-varying effects of pollution on mortality in multi-site time series studies. The methods are applied to the updated National Morbidity and Mortality Air Pollution Study database …

Stroke mortality rates are higher in Brazil when compared to other countries. The city of Sao Paulo has a good system of mortality surveillance that allow us to describe the epidemiology of the stroke in the city. Our aim was to describe the stroke mortality pattern by gender and age characterizing the ischemic/hemorrhagic ratio. We categorized mortality data by gender and a 10-year age-strata from 30-39 years-old to 70-79 years-old. To avoid random variations, we calculated the mean of all deaths occurred during the period of 1997 to 2003. Mortality rates were calculated using the population from the Brazilian National …
